Verified step by step guidance1
Begin by understanding the key processes involved in the central dogma of molecular biology: transcription, translation, and DNA replication.
Transcription is the process where the DNA sequence of a gene is copied into RNA. This does not involve determining the exact order of nucleotides in DNA.
Translation is the process where the RNA sequence is used to synthesize proteins. This also does not involve determining the exact order of nucleotides in DNA.
DNA replication is the process of copying the entire DNA molecule to produce two identical DNA molecules. While it involves copying nucleotides, it does not determine the exact order of nucleotides in a specific fragment.
DNA sequencing is the process that involves determining the exact order of nucleotides in a fragment of DNA. It provides a precise sequence of nucleotides, which is crucial for understanding genetic information.
